It is a registered charity and in the year to 31 March 2019 it had an income of £5.7 million and expenditure of £4 million, resulting in net income of £1.7 million.

The SWT manages twenty-six nature reserves in the county. Nineteen are Sites of Special Scientific Interest, one is a national nature reserve, eleven are local nature reserves, eight are Special Areas of Conservation, three are Special Protection Areas, three are Ramsar sites and seven are Nature Conservation Review sites. Its headquarters at Woods Mill, south of Henfield, is also a nature reserve with a lake, woodland and meadows.

The historic county of Sussex is divided into the administrative counties of East Sussex and West Sussex. The South Downs stretches across the county from west to east. This area is chalk and to the north is the Weald, which is composed of heavy clays and sand. The coast has a succession of holiday towns such as Brighton, Eastbourne, Bognor Regis and Worthing.

Knepp Wildland is the first major lowland rewilding project in England. It comprises 1,400 hectares (3,500 acres) of former arable and dairy farmland in the grounds of Knepp Castle, in West Sussex.

Since 2000 when the conversion from intensive agriculture started, the land now supports many rare species including turtle doves, barbastelle bats, slow-worms and barred grass snakes; it has become a major nesting site for nightingales; a breeding hotspot for purple emperor butterflies; the site of the first white stork chicks raised in the wild in England for 600 years, and is home to the first beavers living in the wild in Sussex for 400 years. On 17 November 2021, the very rare vagrant emperor dragonfly (Anax ephippiger) was discovered in one field.

West Sussex is a ceremonial county in South East England. It is bordered by Surrey to the north, East Sussex to the east, the English Channel to the south, and Hampshire to the west. The largest settlement is Crawley.

The county has a land area of 1,991 square kilometres (769 sq mi) and an estimated population of 915,037 in 2024. The largest settlements are on the coast, and include the towns of Bognor Regis, Littlehampton, and Worthing; the last two are part of the Brighton and Hove built-up area, which extends into East Sussex. The interior of the county is generally rural, and contains the towns of Crawley and Horsham in the north-east and the city of Chichester in the south-west. For local government purposes West Sussex is a non-metropolitan county with seven districts. West Sussex and East Sussex were historically a single county, Sussex.

The South Downs are a defining feature of the county, crossing it from east to west and dividing the north and south. The downs are a chalk escarpment which falls away sharply into the Weald to the north and more gently toward the south, where there is a narrow strip of flat land between the hills and the coast. The coastal strip widens to the west, where it is punctuated by Chichester Harbour, a ria.
